This is the best ebike I've ridden and I have owned and/ or built 6 ebikes over 12 years ( all trottles). The full suspension is great....the battery is removable in seconds....and the battery is 17.5 aHrs....650whrs...50lbs.... MSRP $4600. LOVE IT Before you spend $6000 on the Specialized, or get a Haibike, check out the BULLS. Super quiet. I tried all the major mid drive ebikes....(I demoed Haibikes with Bosch CX, Yamaha and Specialized Levo w/ Brose). E-stream FS3 27.5 is the quietest ....more hillclimbing torque than the Bosch CX or Yamaha IMO. I just did a major uphill, rocky, banked switchback trail and it blew me away with the smooth torque sensor and balance/weight distribution. It felt like I was magnetically held on the trail as I was climbing rocks, effortlessly. Less wheelie prone. On the flats, you determine how much assist and just cruise.....but you must always pedal to keep the assist working. Brakes are incredible. I'm 60 with two bad knees, so I know instantly when the pedal resistance is causing too much pain. Usually level 2 is the best on the trails. There is a "sweet spot" in certain gears at certain speeds for the cadence and torque sensing. It took a day or two to find it, and once I did, the steep climbing is effortless.
